Accuracy and freedom inversion

The relation by which a predictive model scores highest on exactly the behavior a person had least room to vary, and lowest on value-laden choices in new situations. A rising accuracy figure about a person is therefore ambiguous between a better model and a narrower life, and a system that both predicts and acts on its predictions can resolve the ambiguity in its own favor without anyone intending it. The structural consequence is that prediction and steering can each be graded honestly but a system doing both cannot be graded on its predictions, because it is in a position to author the evidence.
